3GPP was developed to make a global third generation mobile phone system specification with the aim to drive file sizes down and have a format that worked across a multitude of different mobile devices. 3GPP are deployed across much of the GSM market.

The 3GPP file stores the video element as MPEG-4 Part 2/H.263/MPEG-4 Part 10 (H.264) and the audio element as AMR-NB/AMR-WB/AMR-WB+/AAC-LC/HE-AAC V1. It is a multimedia container format defined by the Third Generation Partnership Project (3GPP) for 3G UMTS multimedia services. It is used primarily on 3G mobile phones but can also be played on some 2G and 4G phones.

The .ogg file format is a type of audio file that makes use of open source Ogg Vorbis compression. It is supported by devices such as Archos and Samsung but is not supported by Apple iOS devices. The .ogg format has been utilised for the provision of streaming audio. The file format is unlikely at present to take a dominant share of the digital music market due to the synonymous nature of MP3 with digital audio.

The .ogg format is actually a container that potentially allows for different streams of audio, video and metadata. Ogg Vorbis is the compression format. It provides medium to high quality audio at between 16 and 128 kbps/channel and is better quality sound than mp3. The OGG file type is a lossy codec which means that data is discarded as part of the compression technique, resulting in a smaller file size. Ogg files are optimised for music files, but will still be of acceptable quality for speech only files.
